VALVE SEATSNLEM0133S10Check valve seats for pitting at contact surface. Resurface or
replace if excessively worn.
+Before repairing valve seats, check valve and valve guide
for wear. If they are worn, replace them. Then correct valve
seat.
+Use both hands to cut uniformly.

REPLACING VALVE SEAT FOR SERVICE PARTSNLEM0133S111. Bore out old seat until it collapses. Set machine depth stop so
that boring cannot contact the bottom face of seat recess in
cylinder head.
2. Ream cylinder head recess.

Oversize [0.5 mm (0.020 in)]:
Intake 35.500 - 35.516 mm (1.3976 - 1.3983 in)
Exhaust 31.500 - 31.516 mm (1.2402 - 1.2408 in)
Use the valve guide center for reaming to ensure valve seat
will have the correct fit.

3. Heat cylinder head to 110 to 130ÉC (230 to 266ÉF).
4. Press fit valve seat until it seats on the bottom.

5. Cut or grind valve seat to the specified dimensions using a
suitable tool. Refer to SDS, EM-150.
6. After cutting, lap valve seat with abrasive compound.
7. Check valve seating condition.

PISTON-TO-BORE CLEARANCENLEM0141S061. Using a bore gauge, measure cylinder bore for wear, out-of-
round and taper.
Standard inner diameter:
86.000 - 86.030 mm (3.3858 - 3.3870 in)
Wear limit:
0.20 mm (0.0079 in)
Out-of-round (X þ Y) standard:
0.015 mm (0.0006 in)
Taper (A þ B and A þ C) standard:
0.010 mm (0.0004 in)
If it exceeds the limit, rebore all cylinders. Replace cylinder
block if necessary.
2. Check for score and seizure. If seizure is found, hone it.
+If cylinder block and piston are replaced, match piston
grade with grade number on cylinder block upper surface.
SEM085G
3. Measure piston skirt diameter.
Piston diameter ªAº: Refer to SDS, EM-153.
Measuring point ªaº (Distance from the top):
45.0 mm (1.772 in)
4. Check that piston-to-bore clearance is within specification.
Piston-to-bore clearance = bore measurement ªCº þ
Piston diameter ªAº:
0.010 - 0.030 mm (0.0004 - 0.0012 in)
5. Determine piston oversize according to amount of cylinder
wear.
Oversize pistons are available for service. Refer to SDS,
EM-153.
6. Cylinder bore size is determined by adding piston-to-bore
clearance to piston diameter ªAº.
Rebored size calculation:
D=A+BþC
where,
D: Bored diameter
A: Piston diameter as measured
B: Piston-to-bore clearance
C: Honing allowance 0.02 mm (0.0008 in)
SEM069G
7. Install main bearing caps and tighten bolts to the specified
torque. This will prevent distortion of cylinder bores, otherwise
cylinder bores may be distorted in final assembly.
8. Cut cylinder bores.
+When any cylinder needs boring, all other cylinders must
also be bored.
+Do not cut too much out of cylinder bore at a time. Cut
only 0.05 mm (0.0020 in) or so at a time.
9. Hone cylinders to obtain specified piston-to-bore clearance.
10. Measure finished cylinder bore for out-of-round and taper.
